Question

if velocity of a particle depends on time as v= t³+2/√t . Then with what velocity particle at t=4 sec and what is displacement till then ?

Answer 1

at t=4
${4}^{3?} + \frac{2}{ \sqrt{4 } ?} \\ = 65$

Answer 2

HERE IS UR SOLUTION __________________________________________

at t=4 
$\begin{lgathered}{4}^{3?} + \frac{2}{ \sqrt{4 } ?} \\ = 65\end{lgathered}43?+4​?2​=65​$
